My invention mirrors of the type adapted in the mouth of DENTAL MIRROR.

Application filed March 25, 1925. Serial No. 18,234.

relates to improvements in to be inserted a patient and used in conjunction with any source of light to reveal the condition of the mouth which teeth or other parts within could not otherwise be conveniently or thoroughly inspected.

An object of the invention is the provision of a mirror of the character described which is adapted to be and easily after manipulated more quickly having been placed in the mouth of the patient to disclose a relatively great number of parts within the mouth than is possible with a dental mirror of ordinary construction.

A further object of the invention is the provision of a dental mirror having reflecting surfaces provided on the opposite faces thereof and which is adapted when placed within the mouth of the patient to hold the cheek away from time being capable the gums while at the same of use to performthe functions of an ordinary dental mirror.

Other objects and advantages of the invention will be apparent from the following description, considered in con unctlon with the accompanying drawings, 111 which- Figure 1 is a perspective view of the improved dental mirror, in one position for use,

Figure 2 the mirror.

The improved is a transverse section through mirror comprises a substantially flat body 1 which is shown as being substantially circular in outline and as having a pair of substantially the 2 and 3 are dispo with the centers nular rim flanges plates 2 and 3 respectively of same diameter.

Obviously, the plates 2 and 3 may each other and formed as a desired. The body 1 is provided at each of the opposite sides just mentioned with a reflector which may be a plate 3, the glass plates tained in the rim in any suitable known manner,

A handle 8 for supporting and manipulating the body 1 is shown as being a rod-like member having an attaching portion 9 secured in a socket or recess 10 in the periphcry of the body 1, said socket being shown as comprising cooperative shallow radial grooves in adjacent faces of the plates t and 5. The attaching portion 9 extends at an obtuse angle to the remainder of the handle 8. The outer end portion of the handle 8 is shown as being reduced at 11 and as provided with screw threads 12, whereby the handle 8 may be attached to any suitable dental instrument or supplementary handle, not shown, with which it can be used advantageously.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Since the body 1 has reflecting surfaces at opposite sides thereof, it is manifest that the inspection of a greater number of parts within the mouth can be effected by means of the de vice than is possible with ordinary single faced dental mirrors. Moreover, the device can be used in the mouth of a patient to throw or reflect light upon the teeth when the device also is being employed to hold the cheek away from the gums of the patient.

Obviously, my invention is susceptible of embodiment in forms other than that illustrated in the accompanying drawings, and I therefore consider as my own all such modifications and adaptations of the form of the device exhibited therein as fairly fall within the scope of the appended claim.

I claim A mirror of the character described comprising a body formed of a pair of plates of circular outline secured flatwise together with the centers of the'plates aligned, said plates having axially extending rim flanges, mirrors fitting in said rim flanges, said plates having registering radial grooves in their adjacent faces cooperating with each other to provide a radial socket in said body, and a handle comprising an attaching portion secured in said socket, the remaining portion of the handle being rod-like and extend ing at an obtuse angle to said attaching portion and to the plane of said body.
